Rule and Implementation Information for the Aerospace
Industry

Announcements:

On February 17, 2015, the Environmental Protection Agency (EPA) published in the Federal Register proposed amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Aerospace Manufacturing and Rework Facilities. See the table below for the Federal Register notice and a fact sheet summarizing the proposal.

Rules/Regulations

Amendments to Final Rule. New definitions for general aviation and general aviation rework facility, separate coating limits for primers and topcoats used at general aviation rework facilities, and additional changes resulting from public comments on previously proposed (October 29, 1996) amendments to the final rule.

Data Gathering

The following file provides facility-wide emission rates for each of the identified major and synthetic area or synthetic minor sources that submitted data in response to the 2011 data collection survey. EPA took total HAP emissions divided by total gallons of solids from all the material reported at each facility which provided us with lb HAP/gal solids. One approach to addressing all the emission points at aerospace sources is to pursue a facility-wide emission limit similar to what was done previously with Miscellaneous Metal Parts and Products (PDF)(63pp, 413k) or Plastic Parts and Products (PDF)(55pp, 406k). This approach provided flexibility to each facility in those source categories that aerospace facilities may or may not feel necessary.

Aerospace Facility-Specific Emission Rates

PLEASE READ: For facilities identified as “Synthetic Area” in the attached file; please confirm your source’s status as such by reviewing the information provided at the bottom of the spreadsheet in the notes. You may then send an electronic mail message to Kim Teal at teal.kim@epa.gov confirming or revising your status. These responses will determine which sources are to be modeled for the risk and technology review currently underway. If we receive no response, we will leave the facility in and plan to model their emissions.

The following Section 114 Information Collection Request (ICR) has been approved by OMB and is being sent to aerospace manufacturing and rework facilities, that are Major or Synthetic Minor sources of hazardous air pollutants (HAP), in the U.S . The due date for the response is April 4, 2011; if you have questions or concerns regarding this data collection please contact Kim Teal at teal.kim@epa.gov. To provide sources the greatest amount of time possible for responding to the survey we are posting the ICR and instructions below; however, the following forms are intended for hard copy submittal only. If sources prefer to submit their information electronically, they may use the following file transfer protocol (FTP) site:

We have received many questions regarding the definition of electronic components for the purposes of completing the information collection request (ICR) for the aerospace source category. The aerospace rule provided an exemption for electronic components but it did not provide a definition or guidance for "electronic component". Therefore, I suggest that facilities use their best judgment on what constitutes an electronic component. If you have a solid justification, that any reasonable person would accept, for the part or component being an electronic component then please do not report the activities associated with that part or component on the ICR. However, if you question whether or not it would be considered an electronic component then you should report the activities associated with that part or component.

Extension Requests

We have received numerous extension requests to the submission deadline for the Information Collection Request (ICR) for Aerospace Manufacturing and Rework. I have received approval from my management to provide the following relief for submission of data.

April 4, 2011 Major sources must supply only the coating data specific to RTR (i.e., those coatings for which the Aerospace NESHAP provides specific emission limits) modeling needs (see table,Aerospace ICR April 4 2011 data requirements)

May 4, 2011 Major and Synthetic Minor sources must supply all remaining data on the ICR

Aerospace NESHAP Reporting Requirements from Naval Facilities Engineering Service Center (2/12/01 version). NOTE: This document is not sanctioned, nor has it been checked for accuracy, by the EPA. It is being provided for FYI only.

Initial Notification [with example responses]

Notification of Compliance Status [with example responses]

Semiannual/Annual Notification Report [with and without example responses, two files zipped].
Updated 1/4/01 to reflect the 2/8/00 final amendments. All files are zipped.

Note: To use all the functions of the Semiannual/Annual Report in the PDF version, you'll need Adobe Acrobat V4 with Exchange. Adobe
Acrobat Exchange allows you to save any data that you enter onto the PDF form. We are in the process of working with NTIS to make the PDF form bundled with Adobe Acrobat Exchange available
on CD-ROM for a minimal cost. As soon as additional information is available we'll post it here.

Applicability Determination Index (ADI). The ADI is maintained by EPA's Office of Enforcement and Compliance Assurance (OECA) and provides a data base of memoranda dealing with applicability issues. The database is searchable by Subpart.

Aerospace
Sector Notebook. Sector notebooks are developed by EPA's Office of Enforcement and Compliance Assurance (OECA)and contain multimedia information (air, water, and land pollutant
release data) for a specific industry.

Paints and Coatings Resource Center (PCRC). EPA's Office of Enforcement and Compliance Assurance (OECA) has created several compliance assistance
centers for the coating industry. Free membership to the PCRC can be obtained on-line. The PCRC provides regulatory compliance and pollution prevention information topcoating facilities, industry vendors and suppliers, federal, state and local agencies,
academia, and other interested parties. The site does contain information on the aerospace industry. To find aerospace related information, go to "Technical Database", "Search by
Keyword" then enter "aerospace".

National Metal Finishing Resource Center (NMFRC). EPA's Office of Enforcement and Compliance Assurance (OECA) has created several compliance assistance centers for the coating industry. Free membership to the NMFRC can be obtained on-line. Although the NMFRC is geared primarily toward the metal finishing industry, the site does contain information on the aerospace industry. To find aerospace related information, go to "Members", "Technical Database", "Search by Keyword" then enter "aerospace".

Other Compliance Assistance Centers.EPA's Office of Enforcement and Compliance Assurance (OECA) has created several compliance assistance centers in addition to PCRC and NMFRC which may be valuable to industry in obtaining regulatory and compliance information. This link goes to the main compliance assistance center webpage which lists all centers currently available with a brief description of what type of information the center provides.

Aerospace Industries Association (AIA).AIA is a trade association representing manufacturers of commercial, military, and business aircraft, helicopters, aircraft engines, missiles, spacecraft, and related components and equipment. Environmental related information is available at the site.
